I am a self-taught WordPress programmer that has been a wild roller coaster ride that has been full of experiences of major and minor successes as well as huge and numerous minor failures. If you are coding themes, plugins, or actually working on the WordPress developmental team, you will have to eventually work with “The Loop.”
The Loop controls the whole of the WordPress blog and is extremely powerful, yet simple. Unfortunately, for someone that comes into programming with WordPress and does not have anyone there to explain stuff with them, it can be extremely confusing.
Thankfully, we have been given a great visual illustration by wptuts+ that wonderfully shows how it runs and where you will need to make your changes for your own personal site.
